Specification of Letters Patent.

. Patented Apr. 24, 1917.

Application filed ctobe'r2, 1915. serial No. 53,682.

To all whom it may concern:

Be it known thatfiI, GEORGE E. SCOTT, a citizen of the United States, and resident of Chicago, in the county of Cook andState of Illinois, have invented. certain new and useful Improvements in Car-Truck Columns, of which the following is a specification.

My invention relates tocar trucks and has particular reference to an improvement on the column shown in the patent issued to me, No. 1,135,627.

An object in the present construction is to provide for the possibility of the breakageof. one of the bolts which are cast integral withthe column, as shown in my previously granted patent. It has been found that these bolts may be broken off. In the present instance provision is made whereby if one ofthe bolts is broken a hole may be. drilled and a short bolt inserted in place of the one broken off. :If both the threaded lugs are broken two holes maybedrilled and along bolt inserted. The construction in the present design is such that the'thic'kness of the column is reduced to anlextent sufficient to'permit the insertion of either a long or short bolt and an opening is cored through the intermediate web in anticipation of the necessity for inserting a long bolt.

A further object is to provide for a flat I bearing for the top and'bottom arch bars in proximity to the .integralshank of'the bolt, this result being secured by providing a re ces's or enlargement around the bolt at the center. This obviates the necessity for chipping or turning at this point and provides fora bearing for thestraps.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is an elevation of a column constructed in accordance with my invention;

2is a similar view in which thetop lug has been broken off, and a short boltinserted in place thereof; I

Fig. 3 is a similar view showing both the lugs broken 'ofl and a longbolt' inserted through the column; 7 I y I Figs. 4, 5 and 6 are elevations of the eonstruction shown in Figs. 1, 2 and 3, with a portion of the 'top' of the column broken away in each'instance; Fig. 7 isa plan view of the column shown in Fig. 1, with thenut removed,-and,

Fig. 8 is a section on the. line 88 of Fig. 1.

Referring more particularly to the drawings it will be seen that the column may consist ofa front wall 10, side walls or webs 11, and end walls 12. To the end walls are integrally cast, the lugs or bolts 13, the ends ofwhich are threaded to accommodate the nuts. The end walls 12, are recessed or grooved as at 14:, the grooves being shown as extending entirely across the top wall.

The reduction of metal at this point permits the formation of the required fillet and permits of a flat bearing for the arch bars without machining or chipping. Beneath the end walls are located webs 15, and inter mediate. of the end walls is provided aweb '16, which extends transversely of the column. This web is provided with an aper-.

ture 17, for a use which will later be described. It will be noted that the wall 10 is redu'cedin thiclmess, as atv 18, this being best shown in Fig.8, the inner edge of the opening 17, being located. contiguous to the wall at the point of reduced thickness.

In case the upper'threaded lug should be broken, the web 15, is chipped out and a hole drilled throughv the end wall at the proper point to accommodate a short bolt 19, as showninFigQ. As shown in Fig. 5, the head .ofthisi bolt will be cut off at one side to permit it to be accommodated against the wall 10. L In case both of the integral bolts are broken, both the upper and'lower webs 15 are chipped out, holes drilled at the proper point and a long bolt 21, inserted, as

shown at Fig. 3. In this case the bolt extends through the opening 17 ,in the intermediate web and occupies the point of reduced section of the wall 10.

The construction shown is capable of considerable modification and such modifications as are within the scope of my claim I consider within the spirit of my invention.

Iclaim:

A car truck column, comprising a front Wall, two side Walls, two end Walls and a Web parallel with said end Walls and joining said side walls, a fastening bolt integral with each end Wall said end Walls adjacent to F said bolt being grooved, said transverse Web being apertured in a line parallel With said bolts, said front wall being vertically grooved to eliminate metal which Would prevent the insertion of a bolt through the aperture in said transverse Web, the arrangement being such that upon the breakage of one or both of said integral bolts an aperture may be drilled in said end Walls for the accommodation of a separate fastening bolt, substantially as described.

Signed at Chicago, 111., this 27th day of September, 1915.
